depends on FPGA_BRIDGE
depends on HAS_IOMEM
help
Say Y to enable drivers for Xilinx LogiCORE PR Decoupler
or Xilinx Dynamic Function eXchnage AIX Shutdown Manager.
The PR Decoupler exists in the FPGA fabric to isolate one
region of the FPGA from the busses while that region is
being reprogrammed during partial reconfig.
The Dynamic Function eXchange AXI shutdown manager prevents
AXI traffic from passing through the bridge. The controller
safely handles AXI4MM and AXI4-Lite interfaces on a
Reconfigurable Partition when it is undergoing dynamic
reconfiguration, preventing the system deadlock that can
occur if AXI transactions are interrupted by DFX.
